Abstract

Let H and A be the hamiltonian, resp. the modular operator associated with an invariant faithful normal state ω of a W*-dynamical system (A, α). Then Δ = f(h) for some decreasing function f if and only if (roughly speaking) ω is 2-passive with respect to α. It follows that under certain conditions a 3-passive state is an equilibrium (i.e. KMS) state.
